100 reactions

You task is described below but in addition, please could you find a you tube video or other suitable video showing the reaction.

Hydrochloric acid (Hydrogen Chloride) + Ammonia Gas

HCl + NH3 --> NH4Cl

MochiiCake~ ;P (Joce:D)

GUESS WHAT?!!!! I'm doing number 2!!! hehehehe.. :P #100reactions
2. Zinc dust is added to a solution of gold III chloride
3Zn(s) + 2AuCl3(aq) ---> 3ZnCl2(aq) + 2Au (s)
ionic equation: 3Zn + 2Au3+ ----> 3Zn2+ + 2Au
Observation: Silver grey metal dissolves into clear solution. the gold solids will be formed.
